Full eclipse of the Moon this tuesday

There will be full eclipse of the moon visible from Novato Tuesday, August 28th early in the morning. We're going to try to watch it (and take pictures). The San Francisco Sidewalk Astronomers site has all the information here. For even more detailed information, see the lunar eclipse page that NASA has put up here.NASA says you can watch a live webcast of the eclipse(weather permitting) here. Read the MSNBC article here to see why the moon appears red during the eclipse.
If you don't want to stay up late, download the latest version of google earth, which now allows you to search the sky as well as our planet earth.

Final word on Wikipedias "Objectivity"

Wired Magazine has just posted the WikiWatch. Kevin Poulsen writes:

Caltech graduate student Virgil Griffith just launched an unofficial Wikipedia search tool that threatens to lay bare the ego-editing and anonymous flacking on the site. Enter the name of a corporation, organization or government entity and you get a list of IP addresses assigned to it. Then with one or two clicks, you can see all the anonymous edits made from those addresses anywhere in Wikipedia's pages.

Griffith's work is a neat example of what can be uncovered just by reorganizing public information. Wired News writer John Borland has the full story here.

THREAT LEVEL predicts a lot of sad, embarrassing secrets will emerge from this project once netizens dive into it -- and we'd like to be a part of that. So visit the Wikipedia Scanner and do some sleuthing. Post what you find here on our wall of shame, where you can join other Wired News readers in voting submissions up or down. We've seeded the list with a few finds of our own. Happy hunting!


It's an amazing list-the top-rated edit is Diebolds attempt to edit its voting machine record,followed closely by Scientology's edits of its entry...

Wikipedia in the lab

Last year I saw many students using Wikipedia as their source for research they were doing on various subjects. I've already posted once on the other sources we can start showing the kids. Here's a link to a PBS teachers Blog discussion on Wikipedia, and here's an article I found on line that sums up what most librarians have to say on the subject:
Can We Make Peace with Wikipedia?


By Chris Harris -- School Library Journal, 6/1/2007

Every day, librarians around the world turn to the Oxford English Dictionary (OED) as the definitive resource. This trusted authority, however, has a shocking secret—the venerable OED began life as a wiki. Well, sort of. Thousands of volunteer readers back in the day composed more than 400,000 definitions by submitting slips of paper with quotations that detailed word usage. Lacking wiki software meant organizing over five million slips to form this collective intelligence project, a process that lasted from 1857 until 1928. Today, Wikipedia’s volunteers have published about five million articles worldwide in just six years. So these two projects appear to be distant cousins of sorts.

While librarians universally worship the OED, we, as a profession, reject Wikipedia. (See “Wikipedia, the Review,” March pp. 82–83) Many librarians distrust the online work—if anyone can contribute information, the articles will be inaccurate, they say. So many media specialists have banned using the site. There are two problems with this. For one, study after study has found that Wikipedia is, in fact, reasonably accurate as a general knowledge source. And students are just going to use it anyway. My May 2006 column for SLJ “MySpace Can Be Our Space” (p. 30) explored the futility of attempting to ban a wildly popular Web site. Even if you filter Wikipedia and its typically prominent results on Google, students will just use it at home.

In an April 2007 study, the Pew Internet and American Life Project found that over a third of American homes with Internet access are using Wikipedia. Moreover, Wikipedia users are predominantly college graduates (50 percent versus 22 percent of high school graduates). So if a child comes home seeking help with a research project, it’s likely that Mom and Dad will turn to the online encyclopedia. Even if they don’t, a basic search on Google for single word topics almost always includes a result from Wikipedia. Doing a country project on France? Wikipedia’s entry is the first hit on Google. State project on Wisconsin? Again, the wiki article comes out on top.

Many schools have prohibited citing Wikipedia as a source in research papers; and Wikipedia fully agrees with this policy. After Middlebury College’s ban, Wikipedia’s Sandra Ordonez told InsideHigherEd.com that, while “Wikipedia is the ideal place to start your research and get a global picture of a topic, we recommend that students check the facts they find in Wikipedia against other sources.” Ordonez added that, although Wikipedia is a great place to check on something, it is “not a valid resource for scholarly research.”

These are the same concerns that I hear from high school librarians. We cannot, however, continue to reject Wikipedia because we aren’t comfortable with the wiki process itself. Our students and their parents are just fine with it. To be quite frank, continually bad-mouthing Wikipedia to the very people who use it—successfully—makes us look a bit daft. It would be much more productive to teach colleagues, students, and parents how to best use Wikipedia. Instead of appearing to be “behind the times” when it comes to new information sources, librarians can foster educated, high-end users who verify Wikipedia entries using the history and discussion tabs. If we can’t beat ’em, let’s join ’em—as leaders in promoting the proper use of Wikipedia. As such, here are three “rules” regarding the wiki that also serve to enhance research overall:

1) At least three sources are required to verify research.

2) General encyclopedias like Wikipedia are a great place to get started, however …

3) Serious research projects cannot cite general knowledge encyclopedias.
